Document Type and Number:
Japanese Patent JPH0778484
Kind Code:
B2
Abstract:
A fire monitoring system used in a fire alarm arrangement includes a fire receiver and a plurality of fire sensors connected to signal/power supply zone lines from the fire receiver to a plurality of fire warning zones, the sensors for short-circuiting the respective zone lines with a low impedance in case of a fire. An analog detector having an address is located at a given warning zone among the fire warning zones. The analog detector is connected to the corresponding signal/power supply zone line through an analog sensor controller having an operation circuit for calculating an analog signal obtained by address polling from the analog detector.
